Long carbon fork for Colnago 58
 

I need a longer carbon fork for a recnet Colnago 58 C50 model I purchased.
I normally ride 60 to 64 frames.
Its on the small end for me and will fit ok if I can raise the stem higher like I did for the saddle.
Problem is that the previous owner cut so just fits stem headset and no extra left for raising the stem.
Would like a nice fork worthy of this C50.
Would have posted this in the wanted to buy but account does not have priviledge so Im taking a chance here.
TIA for any advice
